1997 Honda civic Dx idling

[Trey Hughes]

My civic when turned over idles high and low back and forth untill i turn my ac on then it idles perfectly i drove it for about 20miles and it died while being in motion could it be my fuel pump and i also pulled the code for a Top dead center sensor. please help.
Also it only idles funny when in park and neutral if that makes anything easier when put in drive or park it's fine until you drive for awhile

Hey my friend, believe it or not it could be an air in your coolant system and a simple bleed off may help, there is an amazing video on youtube, which goes over common idling issues on hondas and way of troubleshooting around them. watch and you should have no problems solving
